I have a 90 day visa for Argentina.  To solve my problem to stay longer we leave the country then return, 90 more days.  So in March 2013 we headed to Asuncion, Paraguay.  We picked that country because Dennis always wanted to go.  Not too much to see and do but we can say we went.  We drove out to a lake that was suppose to be worth seeing and had people who sold local made stuff.  Not much worth buying.  We did find a couple museums in Asuncion. Along with seeing interesting things.
